Alpena Airspace expansion plan is to lower the ceiling to as low as 300 feet in certain areas of Michigan. The expansion proposal comes from the Alpena Combat Readiness Training Center. The goal is to connect Alpena airspace with Selfredge Airforce Base and Camp Grayling. This action is separate from the Camp Grayling proposed expansion, but dovetails with bombing and strafing exercises.

If you check the Anglers Of the AuSable’s Facebook page, one of their members reports finding scrap metal shrapnel in 5 foot craters from aircraft bombing practice, along with piles of bullet casings when hiking to fish.

This impacts the area spanning from Grayling across a large portion of the thumb area and Lake Huron.
